CAUTION: If the system is connected to other customer-supplied equipment, such as a local area
network (LAN) or a remote printer, Samsung Medison cannot guarantee that the remote equipment
will work correctly in the presence of electromagnetic phenomena.
Avoiding Electromagnetic Interference
Typical interference on Ultrasound Imaging Systems varies depending on Electromagnetic
phenomena. Please refer to following table:
Imaging Mode ESD
1
RF
2
Power Line
3
2D or 3D Change of operating mode,
system settings, or system
reset.
Brief ashes in the displayed
or recorded image.
For sector imaging probes,
white radial bands or
ashes in the centerlines of
the image.
For linear imaging
probes, white vertical
bands, sometimes more
pronounced on the sides of
the image.
White dots, dashes,
diagonal lines, or diagonal
lines near the center of the
image.
M Increase in the image
background noise or white
M mode lines.
White dots, dashes,
diagonal lines, or increase in
image background noise
Color Color ashes, radial or
vertical bands, increase
in background noise, or
changes in color image.
Color ashes, dots, dashes,
or changes in the color
noise level.
Doppler Horizontal lines in the
spectral display or tones,
abnormal noise in the
audio, or both.
Vertical lines in the spectral
display, popping type noise
in the audio, or both.
1.
ESD caused by discharging of electric charge build-up on insulated surfaces or persons.
2.
RF energy from RF transmitting equipment such as portable phones, hand-held radios, wireless
devices, commercial radio and TV, and so on.
3.
Conducted interference on powerlines or connected cables caused by other equipment, such as
switching power supplies, electrical controls, and natural phenomena such as lightning.
A medical device can either generate or receive electromagnetic interference. The EMC standards
describe tests for both emitted and received interference.
Samsung Medison Ultrasound System do not generate interference in excess of the referenced
standards.
